This standard provides details on product types, classification by use, test cycles, door mass, corrosion resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the published standard includes annexes with details for special applications.

CE Marking on a product is a manufacturer's declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislations, in practice by many of the so-called Product Directives.

This standard classifies cylinders using a 7 digit coding system. Each digit refers to a particular feature of the product measured against the standard's performance requirements. The standard includes tests on durability, fire and corrosion resistance.

Compression rollers can generally be found on multi-point locks that are installed into PVCu doors. They may be positioned at various intervals along the faceplate of the lock and help to create an even weatherseal down the locking side of the door, thus helping to prevent draughts and water seepage.

Note: Compression rollers are primarily designed to create compression. Should security be priority on the door, Yale recommend multiple locking points be specified i.e. hookbolts.

Also called Door Limiter. A fitment that restricts the door to being partially opened in order to identify callers prior to opening the door for access. Can be either an integral part of the lock mechanism or surface mounted on the inner face of the door.

Also named Door Chain. A fitment that restricts the door to being partially opened in order to identify callers prior to opening the door for access. Can be either an integral part of the lock mechanism or surface mounted on the inner face of the door.

A 16mm groove located on the inside of an aluminium or PVCu door blade profile extrusion. This is a standard feature on most PVCu and aluminium doors and is generally where a multipoint lock will be located.

Typically used on upper floor windows which are difficult to reach. A fully reversible window allows a glazed sash window to rotate nearly full circle within its frame without protruding into the room. When in the reverse position, the outside of the sash can be cleaned from inside the home.

A BSI Kitemark is a trusted mark/symbol of product quality recognized by consumers and specifiers. Kitemarked products have passed a rigorous certification process and can be repeatedly manufactured and supplied to the same standard and purpose for which they were designed.

In addition to this, the products and quality management systems of Kitemark licensees are audited periodically to maintain product quality under ISO 9001: 2000

Describes a type of lock mechanism that has more than one locking point. It usually has a minimum of three locking points (plus latch) spread strategically over the length of the door. Multi-point locks are typically used on PVCu or composite doors.

PQR

A test that covers the security and durability of an entire doorset rather than just the lock. The new annex includes clauses covering materials, construction, tolerance, infill panels and resistance to climatic influences including a thermal cycle test. Assessment is based on the door assembly's ability to continue to operate within specified force limits and a visual inspection for cracking, distortion and delamination.

The spindle is a square metal bar which connects the door handles on either side of your door together through the follower. When the levers of your door handles are pressed, the spindle rotates and operates the latch inside the door, allowing the door to open.

For outward opening sashes in situations where glass may be easily cleaned from the outside of the building. The unobtrusive flush fitting hinges allow the sash to be disengaged and removed when it’s opened to the horizontal position.

The United Kingdom Accreditation Service is the sole national accreditation body recognised by government to assess, against internationally agreed standards, organisations that provide certification, testing, inspection and calibration services.

Yale have a UKAS accredited test house in which many of their products are tested to the required standards.
